Well..i've heard that you can correct them by pinching/pulling their ear a bit when they jump on you..
its kinda what another goat would do to correct them.. (i think...)
Shoot him with a water gun/spray bottle when he does it??
good luck!

pepper spray and tasers are illegal (I think) in NY. I'll have to check out the cattle prod.

I did beat him on the nose, upside the head and where ever else I could make contact....he seemed to like it.
My husband said "punch him in the head" but I'd be lucky to land a punch if he was standing still! I am not a hitter and I guess I hit like a "girl".
